Description

[Technical Field]

[0001] The present invention relates to a drum stand for supporting a molding drum used in a food molding machine, and to a drum stand set including a plurality of such drum stands. [Background technology]

[0002] For example, a food molding device for molding foods such as hamburger steaks and croquettes includes a molding drum having molding recesses formed on its outer periphery into which food ingredients are filled (Patent Document 1).

[0003] There are some sites that use a plurality of different types of molding drums, such as those with different sizes or shapes of molding recesses, or those made of different materials such as resin or aluminum.

[0004] In the past, such sites required users to prepare storage shelves or warehouses for storing unused building drums.

[0005] However, there have been no dedicated products or accessories available to meet such needs, for example, when it is necessary to temporarily store a molding drum before it is attached to the main body of the device or after it has been removed, which can result in a lack of convenience on-site. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2021-65135 Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present invention has been made to solve the above-mentioned problems, and its object is to provide an inexpensive and convenient drum stand on which molding drums used in food molding devices can be placed. [Means for solving the problem]

[0008] In other words, the drum stand of the present invention is a drum stand that supports a cylindrical food molding device drum (hereinafter also referred to as a molding drum) having a molding recess formed on its outer surface for filling food ingredients, and is characterized by having an insertion shaft into which the molding drum is inserted and a support surface that supports the molding drum inserted into the insertion shaft.

[0009] With a drum stand configured in this manner, the forming drum is supported on the support surface when it is inserted into the insertion shaft, making it possible to provide a drum stand with a simple configuration, which is inexpensive and convenient.

[0010] However, after the food molding machine has completed its molding operations and cleaned itself, it may become necessary to mold several additional molded products. In this case, if the molding drum is set back into the main body of the device and molding operations are started again, the device will become dirty and will have to be cleaned again from scratch.

[0011] To avoid this, some sites lay the molding drum flat and manually fill it with food ingredients to form the molded product.

[0012] However, this manual molding requires the pusher for pushing out the molded product to be pushed up against the biasing force of the spring, which is by no means an easy task.

[0013] Therefore, it is preferable that the drum stand of the present invention is configured so that by rotating the molding drum inserted into the insertion shaft, the food ingredients filled in the molding recess are pushed radially outward.

[0014] With this configuration, rotating the molding drum is easier than pushing up the pusher described above, and the molded product can be pushed out more easily, making the drum stand of the present invention more convenient.

[0015] A specific configuration of the molding drum can include one that forms the bottom surface of the molding recess and has an extrusion section that reciprocates between a filling position where food ingredients can be filled into the molding recess and an extrusion position that moves radially outward from the filling position within the molding recess to extrude the food ingredients filled into the molding recess.

[0016] In such a configuration, it is preferable that the drum stand of the present invention is configured so that by inserting the molding drum into the insertion shaft, the force that rotates the molding drum is transmitted to the extrusion section, and the extrusion section is moved between the filling position and the extrusion position.

[0017] With this configuration, the transmission mechanism is formed simply by inserting the molding drum into the insertion shaft, and then, by filling the molding recess with food ingredients and rotating the molding drum, the molded product can be easily extruded without the need for any other operations.

[0018] It is preferable that the transmission mechanism is composed of a roller that is provided on the building drum and moves back and forth together with the push-out portion, and a cam plate that is fixed to the insertion shaft and has a guide surface along which the roller rolls. With this configuration, the transmission mechanism can be made simple, and the manufacturing costs of the drum stand can be reduced.

[0019] It is preferable that the circumferential position of the guide surface on the cam plate is variable. In this case, the molded product is pushed out when the roller rolls on the guide surface, and since the circumferential position of the guide surface is changeable, the position at which the molded product can be received can be changed as needed.

[0020] In order to further improve convenience at a site where multiple types of building drums are used, it is preferable that the insertion shaft be compatible with multiple types of building drums having different shapes or sizes of the building recesses.

[0021] However, if the insertion shaft were to extend vertically, the molding recess of the molding drum inserted onto the insertion shaft would face sideways, which would result in the food ingredients being filled from the side and the direction in which the extruded molded product can be received being limited to the side, which would somewhat impair convenience.

[0022] Therefore, it is preferable that the insertion shaft is inclined so as to gradually decrease from the tip end to the base end. By tilting the insertion shaft in this manner, the molding recess faces up or down as the molding drum rotates, so the position at which the molded product can be received can be changed to any desired position from the top to the bottom. Moreover, since the insertion shaft is inclined so as to gradually descend from the tip end to the base end, the weight of the forming drum can be utilized when inserting the forming drum, which makes the work easier than when the insertion shaft extends horizontally.

[0023] In order to prevent the adhesion of dirt to the building drum supported by the drum stand of the present invention, it is preferable that the drum stand has one or more legs that are placed on a specified support surface, and supports the building drum in a state where it is raised above the support surface.

[0024] In addition, the drum stand set of the present invention is characterized in that the above-mentioned drum stands are stacked in multiple layers, and are detachably attached to the legs, and are equipped with one or more joints interposed between adjacent drum stands to connect these drum stands. With a drum stand set configured in this manner, multiple drum stands can be easily stacked via the joints, making it useful as a storage space for multiple molding drums. [Effects of the Invention]

[0025] According to the present invention configured in this manner, it is possible to provide an inexpensive and convenient drum stand on which a molding drum used in a food molding machine can be placed. [Brief explanation of the drawings]

[0027] Hereinafter, an embodiment of a drum stand according to the present invention will be described with reference to the drawings.

[0028] As shown in FIG. 1, the drum stand 100 of this embodiment is for supporting a molding drum X3 used in a food molding machine that molds food ingredients such as ground meat into molded products such as hamburger steaks.

[0029] Before describing the drum stand 100, a brief description will be given of the food molding machine and the molding drum X3 that constitutes the food molding machine.

[0030] <Food molding equipment X> As shown in Figures 2 and 3, the food molding device X is configured so that food ingredients are introduced into a hopper X1 and an agitator blade X2 inside the hopper X1 is rotated, whereby the food ingredients are pressed by the inclined position of the agitator blade X2 (a position twisted relative to the rotation axis) and pushed into a molding recess H1 in a molding drum X3 located below the hopper X1, and a quantified molded product is extruded while being molded into the shape of the molding recess H1.

[0031] More specifically, the first rotating shaft Z1 to which the above-mentioned stirring blade X2 is attached and the second rotating shaft Z2 to which the molding drum X3 is attached are connected, for example, via a bevel gear, and are rotated synchronously by the driving force from the motor M.

[0032] As shown in Figure 3, an ingredient passage hole H2 through which food ingredients pass is formed at the bottom of the hopper X1, and the molding recess H1, which is located directly above the second rotation axis Z2, is configured to be located directly below the ingredient passage hole H2.

[0033] In the above-described configuration, the rotation phases of the stirring blade X2 and the molding drum X3 are set so that the stirring blade X2 approaches the upper part of the raw material passing hole H2 at the timing when the molding recess H1 is positioned directly below the raw material passing hole H2, thereby pushing the food raw material from the raw material passing hole H2 into the molding recess H1.

[0034] As a result, the food ingredients pushed out through the ingredient passage holes H2 by the stirring blades X2 are filled into the molding recesses H1 and molded according to the shape and depth of the molding recesses H1.

[0035] <3 molding drums> 4, the forming drum X3 is configured to form the food material filled in the forming recess H1 into a ring shape by the forming section X31 and extrude the material radially outward by the extrusion section X32. However, the forming drum X3 does not necessarily have to be one that forms ring-shaped formed products. For example, if the forming drum X3 is one that forms formed products into an oval shape like a typical hamburger steak, a predetermined geometric shape such as a star or heart, or a shape that resembles a living creature, the forming drum X3 does not need to be provided with the forming section X31.

[0036] The extrusion section X32 forms the bottom surface of the molding recess H1 and moves back and forth between a filling position A where food ingredients can be filled into the molding recess H1 and an extrusion position B where it moves radially outward from the filling position A within the molding recess H1 to extrude the food ingredients filled into the molding recess H1.

[0037] More specifically, the pushing portion X32 is, for example, an arc-shaped stainless steel plate biased to the filling position A by a biasing member X33 such as a spring, and is supported by a pair of support members X34.

[0038] The pair of support members X34 have the extrusion portions X32 attached to their radially outer tip ends, and are connected to each other at their radially inner base ends by a connecting member X35 (see FIG. 5).

[0039] In this configuration, a small diameter roller R is rotatably supported on the connecting member X35, as shown in Fig. 5. This small diameter roller R, together with the eccentric cam C (see Fig. 2) attached to the second rotation shaft Z2, constitutes a cam mechanism that converts the rotational motion of the building drum X3 into the reciprocating motion of the extrusion section X32.

[0040] That is, as shown in FIG. 4, this small diameter roller R is provided at a position where it abuts against the outer peripheral surface of the eccentric cam C, and when it rolls on the outer peripheral surface of the eccentric cam C, the phase relative to the eccentric cam C (the radial distance from the axis of the second rotation shaft Z2) changes, and the connecting member X35, the support member X34, and the push-out portion X32 move integrally.

[0041] In the above-described configuration, as shown in FIG. 4(a), when the molding recess H1 is located directly above the second rotation axis Z2, the extrusion section X32 is biased to the filling position A, and in this state, the molding recess H1 is filled with food ingredients.

[0042] When the food ingredients are filled, the molding recess H1 moves toward a position directly below the second rotation axis Z2 due to the rotation of the molding drum X3.

[0043] As the building drum X3 rotates, the small diameter roller R rolls on the outer circumferential surface of the eccentric cam C, and the pushing portion X32 moves from the filling position A toward the pushing position B against the biasing force of the biasing member X33.

[0044] 4(b), when the molding recess H1 reaches a position directly below or in the vicinity of the second rotation axis Z2, the pushing section X32 reaches the pushing position B, and the food ingredients filled in the molding recess H1 are pushed outward in the radial direction. The pushed-out molded product is then transferred to, for example, a conveyor (not shown) provided below the molding drum X3.

[0045] Thereafter, the molding drum X3 rotates again to the state shown in FIG. 4(a), i.e., the state where the molding recess H1 reaches a position directly above the second rotation axis Z2, whereby the pushing section X32 returns to the filling position A, and thereafter the above operation is repeated.

[0046] <Drum Stand 100> 1, the drum stand 100 of this embodiment is capable of leaning the above-mentioned building drum X3 against the drum stand 100. Here, "leaning" means supporting the building drum X3 with its central axis tilted relative to the vertical direction.

[0047] As shown in FIG. 1, this drum stand 100 is used by being placed on a predetermined support surface S, such as the floor or the top surface of a table, and supports the molding drum X3 in a state where it is floating above the support surface S.

[0048] Specifically, as shown in FIG. 6, this drum stand 100 has a support 10, legs 20 extending from the support 10, an insertion shaft 30 supported by the support 10 and into which the molding drum X3 is inserted, and a support surface 40 that supports the molding drum X3 inserted into the insertion shaft 30.

[0049] The support 10 has a strength sufficient to support at least the molding drum X3 inserted into the insertion shaft 30, and specifically has a cylindrical or solid columnar shape with a cross section that is circular, rectangular, triangular, or polygonal.

[0050] The support 10 of this embodiment has a cylindrical shape extending in a direction perpendicular to the mounting surface S, and its bottom surface is placed on the mounting surface S.

[0051] The base end of the leg 20 is connected to the outer peripheral surface of the support 10, extends along the radial direction of the support 10, and the bottom surface of the tip end is placed on the mounting surface S.

[0052] In this embodiment, a pair of legs 20 branching from the support 10 are spread apart so as to gradually move away from the support 10 .

[0053] Each leg 20 has a flat plate member 21, for example, rectangular, extending from the support 10, and a tubular member 22, for example, cylindrical, provided at the tip of this flat plate member 21 and extending in a direction perpendicular to the support surface S, and the bottom surface of this tubular member 22 is placed on the support surface S.

[0054] With the above-described configuration, the drum stand 100 of this embodiment is supported by three points on the placement surface S: the bottom surface of the support 10 and the bottom surfaces of the tubular members 22 of each of the pair of legs 20, and thus stands on its own.

[0055] The insertion shaft 30 is inserted into the central hole Xh of the cylindrical building drum X3, in other words, into the insertion hole Xh in the building drum X3 into which the second rotation shaft Z2 described above is inserted.

[0056] The insertion shaft 30 is inserted into the insertion hole Xh of the forming drum X3 with almost no play, and is cylindrical with an outer diameter approximately the same as the inner diameter of the insertion hole Xh.

[0057] The insertion shaft 30 of this embodiment can be used for multiple types of molding drums X3 having different shapes or sizes of the molding recesses H1. In other words, although the multiple types of molding drums X3 have different shapes or sizes of the molding recesses H1, the insertion holes Xh have a common shape.

[0058] Here, the insertion shaft 30 is inclined with respect to the horizontal and vertical directions when the drum stand 100 is placed on a horizontal support surface S, and more specifically, is inclined so as to gradually descend from the tip end 31 toward the base end 32.

[0059] In the above-described configuration, the drum stand 100 of this embodiment further includes a cam plate 50 fixed to the insertion shaft 30.

[0060] The cam plate 50 is a member corresponding to the eccentric cam C in the food molding device X described above, and is provided at the base end 32 of the insertion shaft 30.

[0061] More specifically, the cam plate 50 here is connected to the support 10 via one or more intermediate members 60, and its front surface 50a, which faces the insertion shaft 30, functions as a support surface 40 that supports the molding drum X3 inserted into the insertion shaft 30, or as an abutment surface against which the inserted molding drum X3 abuts.

[0062] Therefore, the drum stand 100 of this embodiment is configured so that by rotating the molding drum X3 inserted into the insertion shaft 30, for example by hand, with food ingredients filled in the molding recess H1, the food ingredients filled in the molding recess H1 are pushed radially outward.

[0063] Here, as shown in FIG. 7, by inserting the molding drum X3 into the insertion shaft 30, the force that rotates the molding drum X3 is transmitted to the above-mentioned extrusion section X32, thereby forming a transmission mechanism 70 that moves the extrusion section X32 from the filling position A to the extrusion position B.

[0064] More specifically, when the forming drum X3 is inserted onto the insertion shaft 30, the small diameter roller R provided on the forming drum X3 is positioned so as to be able to roll on the outer peripheral surface of the cam plate 50.

[0065] As shown in Figure 7, the outer peripheral surface of the cam plate 50 has a first guide surface 51 along which the small diameter roller R rolls without changing its radial position, and a second guide surface 52 that bulges outward in the radial direction from the first guide surface 51 and along which the small diameter roller R is guided radially outward while rolling.

[0066] With this configuration, by inserting the molding drum X3 into the insertion shaft 30, a transmission mechanism 70 is formed by the small diameter roller R and the cam plate 50, and as the small diameter roller R rolls on the second guide surface 52, the small diameter roller R moves back and forth radially together with the extrusion portion X32.

[0067] More specifically, when the molding drum X3 is rotated to cause the small diameter roller R to roll along the outer peripheral surface of the cam plate 50, as the small diameter roller R moves up from the first guide surface 51 to the second guide surface 52, the extrusion portion X32 moves from the filling position A to the extrusion position B, and as the small diameter roller R moves down from the second guide surface 52 to the first guide surface 51, the extrusion portion X32 moves from the extrusion position B to the filling position A.

[0068] In this embodiment, food ingredients are filled with the molding recess H1 facing a first direction diagonally upward, and then the molding drum X3 is rotated so that the molded product is extruded with the molding recess H1 facing a second direction different from the first diagonally upward direction.

[0069] More specifically, when the molding drum X3 inserted into the insertion shaft 30 is viewed from the axial direction of the insertion shaft 30, the horizontal axis passing through the center of the molding drum X3 (the axis of the insertion shaft 30) is defined as the X axis, and the axis perpendicular to this X axis is defined as the Y axis. Food ingredients are filled into the molding recess H1 located in either the first or second quadrant on this coordinate plane, and a molded product is extruded from the molding recess H1 located in the other of the first or second quadrant.

[0070] However, in this drum stand 100, the circumferential position of the second guide surface 52 of the cam plate 50 is changeable, and the circumferential position of the molding recess H1 when the molded product is extruded can be changed.

[0071] Specifically, as shown in Figure 8, a position change mechanism 80 for changing the circumferential position of the second guide surface 52 is interposed between the cam plate 50 and the intermediate member 60 to which the cam plate 50 is attached.

[0072] The position change mechanism 80 of this embodiment comprises a plurality of holes 81 provided in the mounting surface 61 of the intermediate member 60 to which the cam plate 50 is attached, through holes 82 that pass through the cam plate 50 so as to overlap the holes 81, and fasteners 83 such as bolts that are inserted into the holes 81 and through holes 82 to fasten the intermediate member 60 and the cam plate 50 together.

[0073] The mounting surface 61 of the intermediate member 60 has holes 81 at multiple locations along the circumferential direction, and by overlapping a desired hole 81 with a through hole 82 in the cam plate 50 and fastening them with a fastener 83, the second guide surface 52 can be changed to the desired orientation.

[0074] Specifically, the circumferential position of the second guide surface 52 can be changed, for example, from a position where the molded product is pushed out while facing upward to a position where the molded product is pushed out while facing downward or to the side.

[0075] The position change mechanism 80 may be configured to be able to change the circumferential position of the second guide surface 52 in a stepless manner, for example, by providing a circumferential long hole in one or both of the intermediate member 60 and the cam plate 50.

[0076] <Effects of using a drum stand> According to the drum stand 100 configured in this manner, the molding drum X3 is supported by the support surface 40 when inserted into the insertion shaft 30, so that a simple and convenient drum stand 100 can be provided at low cost.

[0077] Furthermore, since the food ingredients filled in the molding recess H1 are pushed out by rotating the molding drum X3 inserted into the insertion shaft 30, when it is desired to mold several additional molded products, the food ingredients can be pushed out more easily than by manually pushing up the extrusion part X32. The pushed-out food ingredients may be scooped out of the molding drum X3 by hand, or by using a tool such as a scraper.

[0078] Furthermore, the transmission mechanism 70 is constructed simply by inserting the molding drum X3 onto the insertion shaft 30, so that the molding recess H1 can be filled with food ingredients and the molding drum X3 can be rotated to easily extrude the molded product without the need for any other operations.

[0079] Furthermore, since the transmission mechanism 70 is composed of a small diameter roller R provided on the forming drum X3 and a cam plate 50 fixed to the insertion shaft 30, the transmission mechanism 70 can be made simple in configuration, and the manufacturing cost of the drum stand 100 can be reduced.

[0080] Furthermore, since the circumferential position of the guide surface of the cam plate 50 can be changed, the position at which the molded product can be received can be freely changed.

[0081] In addition, since the drum stand 100 of this embodiment can be used for a plurality of types of molding drums X3 having different shapes or sizes of the molding recesses H1, it is useful in workplaces where a plurality of types of molding drums X3 are used selectively.

[0082] In addition, the insertion shaft 30 is inclined so as to gradually descend from the tip end 31 to the base end 32, and the molding recess H1 faces up or down as the molding drum X3 rotates, so the position where the molded product can be received can be changed to any desired position from the top to the bottom. Moreover, since the insertion shaft 30 is inclined, the weight of the molding drum X3 can be utilized when inserting the molding drum X3 into the insertion shaft 30, and workability is improved compared to when the insertion shaft 30 extends horizontally.

[0083] The present invention is not limited to the above-described embodiment.

[0084] For example, although the leg portion 20 in the above embodiment is described as extending in a bifurcated shape, it may extend in a three- or four-pronged shape, or may be flat or block-shaped.

[0085] Although the insertion shaft 30 is described as being inclined in the above embodiment, it may extend along the horizontal direction or along the vertical direction.

[0086] In the above embodiment, the support surface 40 is described as the front surface 50a of the cam plate 50, but it may be provided on a member separate from the cam plate 50. For example, if the insertion shaft 30 extends horizontally, the upper surface of the insertion shaft 30 functions as the support surface 40.

[0087] In the above embodiment, the small diameter roller R is described as rolling on the first guide surface 51 and the second guide surface 52 of the cam plate 50, but it is sufficient that the small diameter roller R rolls on at least the second guide surface 52, and it is also acceptable for the small diameter roller R to remain out of contact with the first guide surface 51.

[0088] Furthermore, the drum stand 100 according to the present invention does not necessarily need to be capable of molding additional molded products as long as it can support the molding drum X3, and in this case, there is no need to provide a cam plate 50 or the like.

[0089] Furthermore, as shown in FIG. 9, a drum stand set 200 including a plurality of the above-described drum stands 100 also constitutes one aspect of the present invention.

[0090] This drum stand set 200 is made up of a plurality of drum stands 100 stacked one above the other in multiple stages, and includes one or more joints 90 interposed between adjacent drum stands 100 to connect them.

[0091] Here, two drum stands 100 are connected by a pair of joints 90, but three or more drum stands 100 may be connected by two or more pairs of joints 90.

[0092] As shown in FIG. 10, the joint 90 is detachable from the leg 20, specifically, it is detachable from the tubular member 22 provided at the tip of the leg 20.

[0093] More specifically, the joint 90 has a cylindrical or solid columnar shape with a cross section that is circular, rectangular, triangular, or polygonal, and in this embodiment, has a cylindrical shape that corresponds to the above-mentioned tubular member 22.

[0094] The lower and upper ends of this joint 90 are provided with fitting portions 91 having smaller outer dimensions than the other portions, and the fitting portion 91 at the lower end is fitted into the tubular member 22 of the lower drum stand 100, and the fitting portion 91 at the upper end is fitted into the tubular member 22 of the upper drum stand 100.

[0095] In addition, here, an inserting portion 11 having a smaller outer diameter than the other portions is provided at the upper end of the support 10, and this inserting portion 11 is designed so that the lower end of the support 10 of the upper drum stand 100 can be inserted into it.

[0096] As a result, a drum stand set 200 is formed in which the drum stands 100 are stacked one on top of the other, and can support two molding drums X3 of the same type or different types.

[0097] According to the drum stand set 200 configured in this manner, multiple drum stands 100 can be easily stacked via the joints 90, making it useful as a storage space for multiple building drums X3.

[0098] Furthermore, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
